Add knowledge graph entity disambiguation guard

[vondutchi]

/claim #17

Summary

• Add kg-entity-alias-disambiguation/, a distinct Scientific Knowledge Graph slice for resolving ambiguous extracted entity aliases before canonical graph merge or edge publication.
• Evaluate ontology candidates from sources such as MeSH, NCBI Gene, PubChem, Wikidata, and GeoNames using confidence, context overlap, candidate margins, and multi-edge risk.
• Emit deterministic reviewer artifacts in JSON, Markdown, SVG, and MP4 form using synthetic data only.

Scope Boundaries

This is synthetic demo data only. It does not call external ontology APIs, DOI services, graph databases, private projects, credentials, or live SCIBASE accounts.

This scope is intentionally separate from existing #17 slices such as broad entity extraction, semantic search, graph navigation UI, recommendations, author graph rendering, ontology export, or knowledge graph dashboards.
